More may be added to the earlier biography.
On the evidence of the subsidy returns of 1436 the Stricklands were the richest gentry family in Westmorland, slightly richer that the Threlkelds and Musgraves.
Sir Thomas was assessed on an annual income of £86 and his son, Walter, on a further £13. These assessments were probably accurate: lands worth 20 marks had been settled on Walter on his marriage in 1426, and in the inquisition taken on the death of Walter’s son, another Sir Thomas (d.1496), the family’s lands were valued at over £80.
The earlier biography speculates that a family matter prompted Sir Thomas to resume his parliamentary career in 1429 after an apparent gap of 25 years, a speculation prompted by his brother Walter’s apparent resort to subterfuge to secure a seat for Buckinghamshire in the same assembly.
Sir Thomas appears to have taken a particular interest in the maintenance of the local peace. The earlier biography cites several examples of his activity as arbiter in disputes involving the leading gentry of his native shire, and he assumed the same function at a much lower social level. In February 1436, for example, he awarded that a yeoman of Hackthorpe, perhaps one of his tenants there, should pay 40s. to a local woman for trespasses committed against her.
Aside from his activity as an arbiter, Strickland took seriously his place on the county bench. Between October 1428 and October 1432 he was paid for attending on 11 of the 18 days on which the justices met, and, judging from other scattered references to his appearances at sessions, a more complete record of payments to j.p.s would reveal a similar picture at other periods of his many years on the commission.
Late in his long career Strickland seems to have developed a strong connexion with the Nevilles. By 1447 he was acting as steward of the manor of Heversham, which lay near Sizergh, for George Neville, Lord Latimer. This was the prelude to a more significant arrangement: on 1 Sept. 1448 his son and heir-apparent, Walter, entered into a formal indenture of retainer with Latimer’s powerful brother, Richard, earl of Salisbury.
